Claims priority, application Netherlands January 21, 1954 2 Claims. (Cl.238349) The invention relates to rail spikes, and more particularly todevices for resiliently urging rails against sleepers.

Various known kinds of resilient spikes have the drawback that theythemselves have to press the rail onto the sleepers, owing to which thespikes have to be eX- tracted entirely or partially for the release ofthe rail. This and the refixing or pressing of the spikes after themounting of another rail is not only a time consuming operation, butalso the grip of the spike legs in the wooden or concrete sleeper willdiminish thereby because the holes are enlarged by such manipulations.

The invention contemplates a so-called direct fastening of the rail, i.e. a fastening in which for the arrangement or removal of the rail themain fastening means, namely a resilient spike, collar screw or the likeremains unaltered in connection with the sleeper and the grip on therail bottom is effected by a clip releasable from the main fasteningmeans.

In these constructions the clip at one side bears on the rail bottom andat the other side on a sole plate, chair, or immediately on the sleeper.The pressing force exerted by the main fastening means herewith actsonly partly on the rail bottom, whereas for the part of ,the clip whichcomes to rest on the sole plate, chair or sleeper a provision is to bemade at the sole plate, chair or sleeper.

The result of the latter is that for each kind of clip only anappertaining sole plate or chair is suitable and universal applicationof a certain clip to various kinds of sole plates or chairs isimpossible whereas known constructions in which direct fastening hasbeen applied cannot easily be converted to the indirect fastening type.

According to the invention the clip is releasably interlaced with thespike in such a manner that the clip will anchor into the spike as soonas the spike starts producing its gripping action, the clip then actingas a unit With the spike.

In a practical embodiment of the invention in which the spike is of thetwo-legs type which through helicoidal windings are connected with abridge piece, and consequently are connected with each other by a loop.The clip is substantially T-shaped, the cross member of the T beingarranged such as to be supported on the inner side of the helicoidalwindings and by means of an ofiset part merging in the vertical part ofthe T in such a manner that the latter may bea r against the lower sideof the bridge piece of the spike.

The resilient clip according to the invention may be arranged in andremoved from the resilient helical spike by lifting the loop over aslight distance by means of a claw wrench and it fastens itself betweenthe rail bottom and the loop as soon as gripping action is given back tothe loop by the loosening of the claw Wrench. The

clip is, as it were, an elongation of the loop which as a result of thepressure produced by the loop clamps the rail bottom to the sleepers.

2,844,326 Patented 22,. 1958 The end of the loop of the helical spikedoes not extend further than to a certain distance from the rail bottom,owing-to which after removal 'of -'the'elips, which may be achievedrapidly with this construction, the rail may be removed quickly andreplaced by another, without the grip of the spike legs in the sleeperbeing unfavorably influenced thereby.

In the drawing:

Fig. 1 is a sectional view of a rail illustrating the engagement thereofby a spike and clip provided in accordance with one embodiment of theinvention;

Fig. 2 is a top plan view of the structure shown in Fig. 1;

Fig. 3 is a view similar to that shown in Fig. 1, illustrating a furtherembodiment of the invention;

Fig. 4 is a top plan view of the structure of Fig. 3;

Fig. 5 is a view, similar to that shown in Fig. 1, illustrating a thirdembodiment of the invention;

Fig. 6 is a top plan view of the structure of Fig. 5; and

Fig. 6a shows, in enlarged scale, a detail of Figs. 5 and 6.

Similar arrangements are useful for soft-wood sleepers with sole platesadequate to soft wood, and for concrete sleepers bearing the railsdirectly by means of a resilient pad.

The resilient spikes shown in the figures have two legs 1 and 2connected by means of helicoidal windings 3 and 4 to a bridge piece 5,which per se cannot press down the rail bottom 6.

This is achieved through a clip 7 which is interlaced in a simple mannerwith a spike.

The clip 7 is substantially T-shaped (vide Figs. 2 and 4) and ispunched, e. g. from strip material.

The cross member 8 of the T, bearing on the parts 3a and 4a of thewindings is pressed downwardly to get a hold against a slanting set up.

Said cross member 8 with an ofiset part 9 merges in the vertical part 10of the T which comes to rest below the bridge piece 5 of the spike andwith its free end engages the rail bottom.

When the parts -3a and 4a of the windings are lifted somewhat with aclaw wrench 11 (Fig. 3)the spike remaining fully in positionthe clip maybe removed.

Figures 1 and 2 show the application of the invention with a sole plate12 which at the same time supports the rail bottomfi laterally and witha concrete sleeper 13.

The extremity 14 of the loop (Fig. 1) here extends beyond the spikelegs.

When one is satisfied with not using sole plates or the like but byhaving the rail rest immediately on the sleeper 16 by means of aresilient pad 15 and to have the lateral support of the rail bottomefiected by the spike legs, the extremity 14 of the loop remains insidethe spike legs as indicated in Figure 3, showing the arrangement forhard wood sleepers. The clip according to Figs. 5 and 6 has a somewhataltered shape. This clip can be manufactured in an easier manner. Herethe clip (see Fig. 6a) has the ends of the cross beam of the T offset at17.

With the clip according to the invention an indirect rail fastening withresilient spikes is achieved in which the grip produced by the spike isfully transmitted to the rail bottom. The unit is independent from theshape or the profile of the sole plates and the like. Also withoutapplication of sole plates and the like an indirect rail fastening isobtained without bolt and nut fastenings. Consequently the constructionis universal. T

What I claim is:

1. A rail fastening device comprising a spike; said spike including twolegs, a bridge piece and helicoidal 3 windings connecting the legs withthe bridge piece; and a substantially T-shaped clip comprising a crossmember supportable within the helicoidal windings and an offset membercoupled to said cross member and supportable against the bridge piece ofsaid spike.

, 2. A device as claimed in claim 1 wherein said offset member is mergedin the vertical part of the T, said vertical part being connected withsaid cross member.
